Application iled May 26, 1897- To a/ZZ wh'om it mag/concern:

Be it known that I, ANDREW W. PATTER- SON, a citizen of the UnitedStates, residing at Aurora, in the county of Lawrence and State ofMissouri, have invented a newand useful Ore-Separator, of which thefollowing is a specification. This invention relates to ore-separatingapparatus of the class embodyingajiigr-'loomv inVv which the mineral isplacedV and immersed in l a tank containing water, the sand, mud, andlight matter being separated from the mineral by the combined action ofthe water and the reciprocating movement of the jig-box.

A principal obj ect of the invention is to obviate the use of a pole forreciprocating the jig-box and saving the operator the time and effortrequired to travel from the box to the end of the pole after eachoperation and replenishing of the box.

A further advantage is to have the parts disposed in as small a space aspossible, so that in inclement weather the operator is protected anda`minimum amount of covering required for housing the apparatus and theattendant.

For a full understanding of the'merits and advantages of the inventionreference is to be had to the accompanying drawings and the followingdescription.

The improvement is susceptible of various changes in the form,proportion, and the minor details of construction without departing fromthe principle or sacricing any of the advantages thereof, and to a fulldisclosure of the invention an adaptation thereof is shown in theaccompanying drawings, in which- Figure 1 is a perspective view of anoreseparator constructed in accordance with this invention. Fig. 2 is alongitudinal section thereof. Fig. 3 is a side elevation having the nearside of the tank broken away and showing the sieve or j ig-box held fromover the vat to permit of access thereto. Fig. 4 is a transversesection. Fig. 5 is a detail view of an adjustable eccentric for varyingthe movement of the jig-box. in perspective of-the guide-bar having thelower portion of theeccentric-yokeapplied thereto. Fig. 7 is a detailview of the perforate bottom or sieve closing the lower end of thejig-box.- p

Corresponding and like parts are referred to Fig. 6 is a detail'view`Serial Nol 638,288. (No model.)

in the following description and indicated in the several views of theaccompanying drawings by the same reference characters.

The tank or body 1 of the apparatus may be of desired form and, asshown, is of rectangular outlineand is subdivided by a transversepartition 2, forming a vat 3 and a sludgebox 4, which are incommunication above the partition, as the latter extends a shortdistance above the middle of the tank or body. The walls of the vat arevertical, which is essential, as will appear presently, to insure apractically close lit between the said walls and the jig-box to insure athorough and rapid lseparation of the mineral. A gate 5 closes anopening in the lower end of the rear wall of the tank, and a similar`gate 6 closes an opening in the lower portion of the partition 2, andboth gates operate in suitable guides,

which direct them in their movements and retain them in place.

Uprights 7 are secured to the sides of the tank near its front end andare provided at their upper ends with bearings in which is j ournaled ashaft 8, provided at one end with a band-pulley 9 and driven by means ofa belt 10 from a band-wheel 11 on the end of a shaft 12, journale'd inbearings at the rear end of the tank, said shaft 12 being driven bylhand or in anyway desired. Y Plates or disks 13 are secured to the endportions of the shaft 8 and have disks 14 adj ustably connectedtherewith and forming' the eccentrics by means of which the jig-box isactuated. The disks or eccentrics 14 are secured to the inner faces ofthe plates or disks 13 in such a manner as to admit of their adjustmentto vary the movement of the ljig-box within certain limits and are heldin place by bolts or similar fastenings 15, passing through the platesor disks 13 and operating in slots 16 of the eccentrics 14, said slots16 being disposed in parallel relation and upon opposite sides of anintermediate slot 17, which aords clearance for the shaft 8, so as toadmit of the eccentrics being shifted to the desired position whenrequired. Yokes 18 coperate with the eccentrics 14 to transmit areciprocating motion to the jig-box. The guide-bars 19 have connectionwith-the yokes and have the lower portion thereof formedtherewith andare pro- IOO vided with longitudinal slots 2O anda lateral cuff 21 attheir lower ends, through which bars 22, secured to the jig-box, areadapted to operate. The bars 22 are secured at their lower ends to theends of the jig-box and have pins 23 at their upper ends to operate inthe longitudinal slots 20, whereby the jig-box is caused to movevertically without causing any binding between the bars 22 and the cus21 when the boX is raised and lowered with reference to the vat 3.

The j ig-box 24C may be of any desired shape and is oblong and ofrectangular form, and is of such relative dimensions as to t easilywithin the vat 3, so as to move therein when reciprocated. This box ispreferably metallined in order t0 render it more durable, and the bodyis composed of wood for the sake of lightness. The bottom of the jig-boxis closed by a screen or plate, the latter formed with a series ofperforations 25, which are contracted at their upper ends and flareoutwardly and downwardly to prevent the lodging and wedging of anysubstance therein, as any matter which will readily pass through thecontracted end of the openings will not bind because of the Hare givento the walls of the openings. Plates 26 are hinged or loosely connectedat their upper edges to the sides ofthe jig-box and have their loweredges bent inward, made rounding, or otherwise constructed so as not toengage with the sides of the vat to check the descent of the jig-bor.therein. These plates are intended to swing outward at their lower edgesand ride upon the inner walls of the vat, so as to secure a practicallyclose fit between the jig-box and vat, whereby the water is compelled topass through the perforate bottom of the jig-box when the latter isreciprocated and lowered therein, whereby the light matter-such asearth, sand, and sludge-is carried off. An opening 27 is formed in therear side of the jig-box and is closed bya gate 28, which operates insuitable guides, and this opening when uncovered admits of the water andiine sand in the upper portion of the jig-box escaping into thesludgebox just prior to removing the mineral from the jig-box. A plate29 is hinged at its upper edge to the rear side of the jig-box, at apoint below the opening 27, and normally occupies a pendent position andhas connection with the gate 28 by means of a cord or chain 30, and whenelevating the gate 28 to disclose the opening 27 the plate 29 is broughtfrom a pendent to an inclined position, whereby the water and `sand aredirected into the sludgebox and prevented from entering the vat.

The j ig-box, in addition to its reciprocating movement in the vat, isadapted to be raised and lowered to admit of the separated ore be-4 ingremoved therefrom and the ore to be separated or treated suppliedthereto, and to attain this end the jig-box has connection with awindlass 31 at the front end of the tank by means of cords or chains 32,the latter being connected at their lower extremities with the ends ofthe jig-box and passing over sheavepulleys 33, loosely mounted upon theshaft 8, the opposite ends of the cords or chains being connected withthe windlass to be wound thereon for raising and lowering the jig-box,as may be required. A ratchet-wheel 34 is secured to one end of thewindlass and its teeth are engaged by a pawl 35, whereby the jig-box isheld in an adjusted position. A crank 36 is applied to the windlass andenables the latter to be turned for regulating the height of the jig-boxwith reference to the tank or vat. By having the sheave pulleys 33loosely mounted upon the shaft 8 the latter is enabled to turn withoutchanging the relation of the pulleys, the frames or blocks of the saidpulleys being provided at their ,upper ends with bearing-sleeves,through which the said shaft 8 passes.

The ore to be separated after being crushed or otherwise suitablyreduced is supplied to the jig-box, the latter being elevated for thispurpose, and when suiiiciently loaded the jigbox is lowered into the vatby means of the windlass, and the shaft 12 being rotated either by handor other suitable power the jig-box by reason of the eccentrics 14: andintermediate connections has imparted thereto a reciprocating motionwhich settlesthe mineral and loosens the slime, sand, rbc., which lattermay be drawn off through the opening 2.7 or flow over the sides of thejig-box, as required. The fine ore or mineral will pass through theperforate bottom or sieve of the jig-box into the vat and may becollected, when required, by elevating the j ig-box and pushing it toone side and holding it in this position by means of a brace 37, asindicated in Fig. 3. The sludge-box is cleared of the slime by openingthe gate 5, and the vat 3 is subsequently cleared by opening the gate 6,as will be readily understood.

When the jig-box is lowered into the vat to the limit of its movement,the p ins 23 engage with the lower closed ends of the slots 2O andsupport the j ig-box, and the cords or similar connections 32 areslackened to permit of the jigging motion of the box upon operating theshaft 8 in the manner set forth.

Having thus described the invention, what is claimed as new is 1. Inapparatus for separating ore, the combination of a tank, a jig-box,` ashaft having an eccentric portion, connections between the jig-box andeccentric portion of the shaft and comprising parts slidably related andhaving a limited movement, and means independent of the suspending andjigging mechanism for raising and lowering the jig-box and moving theparts comprising the slidable connections, substantially as set forth.
